Haibane avs script reality check?

I've been messing around with processing options for this footage, and I think I've found a satifactory setup, but thought it would be wise to ask if I've done something terribly wrong before I start encoding clips at 1.5 fps.

Code: Select all

mpeg2source("D:\hrdisc3\hrdisc3.d2v",cpu=4)
LanczosResize(848,480)
KernelDeint(order=1,threshold=255,sharp=true)
temporalcleaner()
deen("a2d",2,6,8)
mftoon(strength=128)
ConvertToRGB32()

That's the best I've come up with to make huff clips, it looks fine to me.

As far as I've been able to figure out, the show was animated at film rate, but directly encoded as interlaced NTSC. Even with no attempt at deinterlacing, no combing is visible anywhere except stuff like the credit rolls, and maybe one or two little bits of CG based stuff. If I need those scenes, changing KernelDeint's threshold to 10 takes care of it just fine.

The aim here was to keep smoothness on all the pans, etc. by converting to 29.97 progressive, and editing with that.
Have I missed anything important with the way, I've set it up? can I/ do I need, to add anything like AssumeFrameBased, to convince huff/Premiere that I'm feeding it 29.97 progressive? As far as I can tell, I am.

Just thought I'd make a shout out for any suggestions on working with this footage before digging in to lots of time and disc hogging encoding. Any suggestions or comments are welcome.

You should resize, *after* you deinterlaced.
IVTC, Deinterlacers and such work best, when applied first, before anything else could meddle with the combed lines.

BTW: I once tried to IVTC Haibane Renmei, and while the pans came out a little jerky I didn't find it that annoying. I expected more stuttering ,considering the horror-stories I heard from people that tried to IVTC it, when it was still released as a fansub.

I tried deinterlacing first, and to me the footage actually looked the same/slightly worse. It shouldn't really make much of a difference either way, since the resize I used preserves the vertical resolution.

Actually it's ok to resize before you deinterlace provided you are not resizing vertically (which you are not).

There was actually a reason I thought it might be good to resize first, I figured since the footage is anamorphic, the horizontal stretching would accentuate any combing, making it easier for whatever deinterlacing method I used to find any, with less chance of undetected little nubbins getting made bigger by resizing. Forgot to mention that in the earlier post, and I'm not sure it would matter anyway.

Ah well, I threw a test clip into Premiere, made a cut or two, and exported, nothing blew up, so I guess I've found happiness with my script.

Absolutely correct. It's just that this filter-order automatically rang my alarm bell >.<°
